This plainly but richly-coloured butterfly, which appears 
to be confined to a very small district in south-eastern 
China, is one of the most abundant and characteristic 
insects of Hong-Kong, and it is strange that it should 
have been a rarity, even in the best collections, for so 
long a time. It was almost the first butterfly which I 
saw on my arrival in December, 1891, and worn speci- 
mens were to be met with throughout the following 
months, a fresh brood appearing on March 12th. Even 
on dull cool days it may be seen on the wing, flying close 
to the ground in shady places with a slow, irregular, 
flapping flight, and frequently settling arcong dead leaves 
and in damp spots ; stragglers are not rarely seen in the 
streets of the city. It is not always easy to obtain in good 
condition, as its delicate structure renders it very liable to 
damage. I have not been able to find the larva, but it 
probably feeds on grass or dwarf bamboo, as in March, 
1892, I found an empty pupa in a small patch of the latter 
plant, just vacated by the perfect insect, which was drying 
its wings close by. The pupa is nearly smooth and with- 
out projections, except two small diverging horns in front 
of the head, and is pale whitish-green in colour.

(1757). 
Of very doubtful occurrence in Hong-Kong; Mr. 
Skertchly, who is perfectly familiar with the insect in 
British North Borneo and elsewhere, saw what he 
imagined to be Amathusia phidippus near the Cathedral 
in Victoria, in December, 1892. The coco-nut palm, on 
the young leaves of which the larva feeds {fide Dr. Hors- 
field), is planted in a few places near Victoria and at Kow- 
loon, but does not flourish.
